Value mapping in UDF?

Hi Guys,
Is it possible to do the value mapping in a UDF.
ReceiverService at runtime - X --> Value mapping not maintained
ReceiverService - Y ---> Value mapping maintained. I want to use this receievr service.
There are more than 300 VM groups and i dont want all the new receivers to add and i want to handle them in UDF
the value mapping picks the receiver service always from the runtime and i want to handle this in UDF and use a different
receiver service. Is it something possible? any help or suggestions would be appreciated
Thanks,
Srini

Hi Srini,
You can go for Value Mapping Replication for Mass Data as described in these links-
/people/udo.martens/blog/2009/04/03/value-mapping-replication-scenario
http://help.sap.com/saphelp_nw70/helpdata/en/2a/9d2891cc976549a9ad9f81e9b8db25/frameset.htm
JDBC lookup is also one option in your case. Have a look at similar discussions for other approach -

Value mapping in xslt mapping

Hi,
I have 2 mapping program one is main .xsl program and other one is value mapping program .xsl .
I have zipped both the program and imported into Imported archive in IR but while testing in interface mapping i am getting error.
error:could not compile xslt stylsheet.
Some of the interface having one .xsl program and value mapping is also defined in the main program itself,these interface i am able to execute successfully but unable to execute wherever there are 2 program (main prog + value mapping).
It seems that value mapping is not loading / executing.
Can anyone please guide me how to call value mapping using xslt mapping?
Thanks,
Subbu

Hi Prateek,
Thanks for the response.
Yes i have 2 program and both needs to execute in one interface mapping.
First program (main) is MappingMOAPS_SAVEMULTIPLE2013.xsl and second program i.e (value mapping) MO_vmf.xsl.
From main program itself value mapping program is called.
Please look below code for main & value mapping prog.
In main prog this is the parameter (<xsl:import href="MO_vmf.xslt"/>) where value mapping prog name is mentioned.
I have already zipped and imported but while testing in interface mapping it is giving error that "could not compile xslt stylsheet".
Could you plaese tell how to check or make XSL to accommodate multiple mappings?

Table lookup instead of fixed value mapping

Hi Folks,
My current scenario is that I have used fixed value mapping to map a single target field. These details are actually maintained in the TP_Code table in R3 (a sample table).
TradingPartner:SAP:Short Text
PA:PA:Package
PL:PAL:Pallet
The table contains 20 entries.
I am thinking that fixed value mapping is not a good option since there might have future changes in the TP_Code table.
Is rfc lookup a good option? But I am not sure which rfc to use and if there is any udf availble to be used in parsing the xml payload.
Please advise.
Thanks a ton!

Thanks so much for the links!
I managed to use and run the RFC lookup to an R3 table using JCo. However, I am not getting the right result.
I am getting the result in this format -> 800,PA,PAC,Package
The correct output is PAC which is the third node. Could this only be achieved by using java tokenizer?
The code that I have used is as follows:
Import com.sap.mw.jco.*;
//write your code here
String DBTABLE = a;
String WHERE_CLAUSE = b" = ""'"c"'" ;
String sapClient = "xxx";
String hostName = "nnnxxx";
String systemNumber = "xx";
String userName = "nnnnn";
String password = "******";
String language = "EN";
JCO.Repository mRepository;
JCO.Client mConnection = JCO.createClient(
               sapClient,
               userName,
               password,
               language,
               hostName,
               systemNumber );
// connect to SAP
mConnection.connect();
// create repository
mRepository = new JCO.Repository( "SAPLookup", mConnection );
// Create function
JCO.Function function = null;
IFunctionTemplate ft = mRepository.getFunctionTemplate("RFC_READ_TABLE");
function = ft.getFunction();
// Obtain parameter list for function
JCO.ParameterList input = function.getImportParameterList();
// Pass function parameters
input.setValue( DBTABLE, "QUERY_TABLE");
input.setValue( "," , "DELIMITER");
//Fill the where clause of the table
JCO.ParameterList tabInput = function.getTableParameterList();
JCO.Table inputTable = tabInput.getTable("OPTIONS");
inputTable.appendRow();
inputTable.setValue(WHERE_CLAUSE,"TEXT");
mConnection.execute( function );
JCO.Table valueSet = function.getTableParameterList().getTable("DATA");
String resultSet = valueSet.getString("WA");
mConnection.disconnect();
return resultSet;

Lookup value mapping table through message mapping.

Hello All,
I am working on a graphical mapping (message mapping). When trying to map the source message to the target message, I need to find out it a particular <b>key</b> exists in the <b>value mapping table</b>. Depending on the result, I need to map different source fields to the target field.
Is there any inbuilt function which will allow me to do a lookup on a value mapping table, or is it possible to lookup a value mapping table from a UDF?
Please help!

Value Mapping and Lookups

Hi all,
I know something about Value Mapping.
And I heard that the Lookups (DB and RFC) are types of Value Mapping.
I am confused how value mapping is related to lookups.
Request you all to provide me some information regd.this.
Thank you.
Regards
Krishna.

Hi,
All the links above are quite useful in understanding Value Mapping and RFC lookups.
Both solutions could be used for getting values from R3 tables at runtime. However, there's difference in way both operate.
RFC lookup is performed at runtime, since it is executed from the UDF in message mapping. Thus at runtime, call is made to R3 table and value is fetched.
In value mapping replication, Value Mapping program is run from SAP R3 and values from table are updated in XI Runtime Cache. Thus at runtime, while performing message mapping, call to R3 system is not made. Values are available in XI cache.
Thus, it is quite obvious that Value Mapping is more performace efficient since it doesn't make a call to SAP R3 system for each incoming message. If the table data does not change very frequently(since for every change value mapping scenario has to be run for update of XI cache), and it is not very large, then it is a good option as compared to RFC lookup.
However, in cases where either data is frequently changing in table or the volume of data is too large, RFC lookup should be prefered choice.
Hope it would be helpful.
Thanks,
Bhavish

Value mapping.

hi
sdn experts,
could you please explain about value mapping?
where the value mapping is used?
thanks in advance.

Hi Chinna Rao,
Value mapping means mapping the data of some source fields to some target fields, in this mapping data can be transform in the format you required for your target system. You can do a value mapping simply by graphical mapping, using UDF etc
Go thru this thread which talks about value mapping:
Value mapping
Value mapping : value mapping function to map different representations of an object to each other. You save the mapping rules for different objects in a value mapping table.
we have two types ,
And Value mapping is used to map different representations of an object to each other.

Value Mapping issue in PI 7.4

Hi All,
We are working on value mapping in PI 7.4. We have a requirement where we should map same target value for different input values (n:1).
Example:
AA     10
BB     10
CA     30
CC     30
CD     30
BA     20
Could you please let us know what are the ways to achieve this?
Thanks
Nishant

Hi Nishant,
Since the key and value pair maintained within a valuemapping group should be unique.
We can try this
AA     1:10
BB     2:10
CA     1:30
CC     2:30
CD     3:30
and a simple UDF after the Valuemapping in ESR

How to pass dynamic values to value mapping? please help!

Hi Experts,
I have requirement where I am using email adapter to send emails. Now the "To" email address is different for different environment. In other words:
DEV - [email protected]
TEST - [email protected]
PROD - [email protected]
When the XI code is migrated to TEST environment the email address will be [email protected] and in production it will be [email protected]
Similarly, there are many more environments.
Now to handle this I have decided to use value mapping where Agency refers to the type of environment.
Now my problem is how do I use it in message mapping.
I have wriiten a java function that returns me the type of environment. But now how to use this value for value mapping. I mean when using value mapping in message mapping we hardcode the agency (environment type).
Is it possibel to specify a variable in value mapping for agency. The variable will be populated by java function before connecting to value mapping?
Please help!
Thanks
Gopal

Hi Gopal,
why don't you use a "if" after your UDF. Depending on the return parameter of the UDF you call different value mappings?

Runtime value mapping

hey ,
The requirement is like a record is being accessed from the database through a JDBC adapter into XI.In the record there are different fields concatenated as a string and these fields are to be mapped to the target side i.e Idoc which can be done by extracting the fields according to the length using substring function.Now, some src fields say   "code" "sign" "cause "
are having some combination of values and these combinations are deciding the value of other fields Mv_TYP MV_REAS COSTCENTER GM_CODE MVT_ IND
in the Idoc .i.e runtime value of these three fields is deciding the value of other fields in the Idoc.
e.g
Source
Description Sign Cause Code
1PO/STO            +   1     none
2rvrs PO/STO   -   1     none
3returngoods   +   1     none
4RevrsRtrnGoods     - 1     none
5RvrsScrap     + 1     none
6Qty2Qlty     - 6     none
Corresponding target
Mv_TYP MV_REAS COSTCENTER GM_CODE MVT_ IND
101     none               01     B
102     none               01     B
202     1072     511100          03
201     1072     511100          03
552                    03

How to do the value mapping so as to have the runtime value of src in the target fields in the Idoc

Hi Indu !
If your mapping values are fixed, and a few, you can put them manually in the Integration Repository, using the standard FixValues function within graphical mapping.
Otherwise, you can use the ValueMapping standard function of graphical mapping to access Value Mapping Groups (loaded by hand or dynamically) in Integration Directory.
If this kind of value mapping doesn't fit your requirements, you can call an RFC or JDBC query via an UDF to query an external data source to map src values to target values.

Matias.

How to identify there is no translation value in Value Mapping

Hi ,
I am using value mapping to translate one of the fields of data. Whenever the input has a translation value, the output is the translated value. But when there is no translation value for the given input in the runtime cache, the output is the input itself. But my requirement is to either error out or send a blank value as output when it doesnt find a corresponding translation value for the given input.
Example:(A,1)(B,2)(C,3) are the values present in the value mapping runtime cache. When the message looks for value mapping for A , as expected it gives an output of 1. Similarly for B and C.
But if the input is "Z", the output is "Z" since there is no lookpu value fo r"Z",which is an anamoly.
Please let me know if you had a prioir experience on this issue and a solution to this.
Thanks,
Valli.

Value Mapping Table - XI MDM Design Question

Hi All,
I have a scenario as :
When XI receives data from a sender system,before sending data to receiver system (in this case MDM),XI is supposed to check some fields in MDM and depending on the result XI should decide whether to send the records or not.
Now,in this case I have two options:
1.After recieving data from sender system ,from XI mapping call a webservice(webservice is supposed to go to MDM and check the fields and give the result),then depending on the result XI will decide whether to send or not.
2.After receving data from sender system,from XI mapping access a value look table in XI from a UDF and then check the result,then depending on the result XI will decide whether to send or not.
I have pointed out some glitches for every option:
1.First considering volume of XI source message( approx. 800 records per message),then MDM database records (approx 40000 or 50000).Hence once XI receives message XI will have to go to MDM for every record and every time it will search among 40000 MDM records using webservice.
This will effect performance as for every record webservice will be called and again it might face connection problems.
2.In this option XI will have to store all the 40000 records from MDM in the value lookup table.Again,how to synch up this value lookup table with MDM database?
This table has to be a copy of MDM database which changes everyday.
Is it ok to store around 40000 records in XI's value lookup table?
Considering above points can you please help me to find out optimum solution?
Thanks,
Shweta.

>>Is it ok to store around 40000 records in XI's value lookup table?
its advised to use value mapping for static values,not for dynamic values,since you will have changes everyday you should not use Value mapping here.
now coming to your first approach,why not copy this table from MDM to XI(i know XI is not the owner of data,but if its an internal MDM server,you should be able to do it),once the table is copied in XI itself,you can simply use ABAP mapping to create the receiver structure.
the above approach looks good to me as long as the MDM guys don't have any problem with XI storing the data as well and you sync up the table between XI and MDM periodically
Thanx

Value Mapping replication GUID Logic

HI,
We are doing Value Mapping replication from ECC table entries to Pi Runtime Value Mapping cache.
We are generating the Group ID required for Value Mapping from ECC.
Here we are confused with the logic for GUID Generation.
At first I thought the driving factors are -- if there is already an entry for the same Source Agency, Source Scheme, Target Agency, Target Scheme and Target Value then it should go in the same group id, else a new gr id needs to be generated.
However it looks like that is incorrect.
Can somebody help us on what should be the logic for generating group id for Value mapping replication.
We have the scenario where the same source Agency, Scheme ,Value maps to multiple target Schemes... and it is not working if we have different Group ids...
Thanks,
Himadri

> We have the scenario where the same source Agency, Scheme ,Value maps to multiple target Schemes... and it is not working if we have different Group ids...
If you want to have multiple targets, then you have create pairs with unique GUID
like this:
A - 1 GUID X
A - 2 GUID Y
A - 3 GUID Z
The standard value mapping function does not work, when you have multiple targets. It will not return an entry.
You have to create a UDF for this purpose. You need to identify which target do you want to select from different values.
An UDF could look like this extract:
IFIdentifier source = XIVMFactory.newIdentifier(source_context,source_agency,source_scheme);
IFIdentifier target = XIVMFactory.newIdentifier(target_context,target_agency,target_scheme);
IFRequest request = XIVMFactory.newRequest(source,target,sourceValue);
try{
IFResponse response = XIVMService.executeMapping(request);
if (response.countTargetValues() > 0){
String[] targetValues = response.getTargetValues();
// take first value of result
return targetValues[0];
This example is taken from PI 7.1

Value Mapping Replication - XIVMService.execute() search using wildcards

Hi, i'm replicating value mappings to IS' cache.
Replication works fine. Using RWB i'm can list all the data in the Value Mapping Groups cache. I can also perform a loose search entering something like "12*" in the 'Value' field and the result contains all the mappings having 'Value' staring with "12".
The problem arises when i try to do the same search with
XIVMService.executeMapping
because it just tries to do an exact search insluding the wildcard as the source value. Has anyone tried this? I need help urgently, otherwise i'm afraid i'll have to change my solution radically.
Thanks in advance
Nicolá

>I can also perform a loose search entering something like "12*" in the 'Value' >field and the result contains all the mappings having 'Value' staring with "12".
Are you doing this to manually search for the value in the RWB or is it in the Runtime.

Where are you trying this search? What i mean to ask is in the runtime ? Are you using some UDF/ Java code to read the data from the value mapping table?
If my answer/ question is completely off track , I would really like to know what you are trying here

SAP XI 3.0 Same source for different target in std Value mapping function

Hi,
We have replicated 4 value mapping entries from R3 to XI having the same Context , Agency , Schema and value for source, but each of the 4 values has the same Context and Agency but different Schema and Value respectively.
To illusstate :
Source                             |Target
Context Agency Schema    Value -----Context Agency   Schema     Value
CS1      AS1      SS1      1        CT1       AT1      ST1       A
CS1      AS1      SS1      1        CT1       AT1      ST2       A
CS1      AS1      SS1      1        CT1       AT1      ST3       B
This value mapping is not working and we always get the source value as the result.
We are wondering if the reason for this is that we use the same source for different targets. But we are not 100 % sure of it.
When I read the documentation on Value mapping or when we use the value mapping standard function in graphical mapping, we pass the context , agency and schema of the source and target respectively and the source value to get the target value, and this combination is always unique in our case as seen in the above example.
Has anyone faced this kind of an issue, if yes I would appreciate if anyone could help us resolve this problem.
Thanks in advance.
regards,
Advait

Hi Advait,
From the below what I understand is that you are not able to do value mapping for the follwoing
1     A
2     A
3     B
As value mapping allow one to one mapping only. Please do it like as mentioned below
1     1*A
2     2*A
3     3*B
Then in the graphical mapping of Integration Repository do the mapping for the same as shown below
source field > VALUEMAPPING> UDF--> TARGET Field
In UDF suppress the value of 1* , 2* , 3* which can be done as follows
create one UDF with one input field
//write the code as below to suppress the field
return input.substring(2);
Here the davantage of using 1* , 2* , 3* etc is that you have the option to use value mapping for 100 values which I think is not normally the case for any Interface.
If you have same source you can do the same thing for that.
Hope this helps you to resolve your query.
Thanks & Regards

ABAP Mapping with Value Mapping

Hi folks,
Anyone knows if it is possible to query a value mapping table inside an ABAP mapping?
Thanks in advance,
Ricardo.

Hi Bhavesh,
Thanks for your prompt answer.
Im already using the Value Mapping with Master data Replication on several graphical mappings. Unfortunately, some changes happened for one mapping program, the complexity increased and the graphical mapping doesnt fulfill these new requirements. So, I thought to use ABAP mapping, because is a language that I know well.
I understood your concern; we are talking about two levels, ABAP and Java stack. It will be needed a call from ABAP stack to Java Stack, but maybe there is an API for that? But, about system performance, I guess Value Mapping its better then RFC lookup, right?
My mapping problem is: I need to generate two nodes (not a field) every time the code MODI (modification) comes in a source field. Inside these two nodes, I have to fill a field, into first node, with an old id and for the second node with the new id.
I cant found any standard function to fulfill this requirement. Maybe this is easy with UDF, but Im not filling comfortable with Java and I dont know how to do it. If you know, please let me know.
Thanks in advance.

Ricardo.
